LED 像素矩阵显示字母

大特写微距摄影：大间距 RGB LED 矩阵屏幕，显示单词 「播放」，经典 5x7 像素字体风格——每个 LED 点直径约 8mm，间距 12mm。字母对应的 LED 以全亮度发出鲜艳暖橙色 (#FFA500) 光，周围关闭状态 LED 镜头在前景呈现凸面亚克力半球结构。面板 PCB 底板为哑光黑色。100mm 微距镜头垂直面板正面拍摄，f/4，约显示 12 列 8 行。亮起的 LED 有紧凑荧光粉光晕与微色差光晕闪烁。关闭 LED 为深哑光黑。色调：鲜艳琥珀橙 #FFA500、深哑光黑 PCB、半透明亚克力灰穹顶、紧凑暖色光晕。

A close-up macro photograph of a large-pitch RGB LED matrix panel displaying the word "PLAY" in a classic 5x7 pixel-font character style — each LED dot approximately 8mm in diameter, spaced 12mm apart. The active LEDs for the letters glow at full brightness in a vivid warm amber-orange (#FFA500), surrounded by the dark off-state LED lenses that show their convex acrylic dome surfaces in the foreground. The panel's PCB substrate is matte black. Shot with a 100mm macro lens, f/4, with the camera perfectly perpendicular to the panel surface, slight field-of-view compression showing about 12 columns and 8 rows. The lit LEDs have a tight phosphor glow halo and a subtle chromatic-aberration micro-flare. Adjacent OFF LEDs are deep matte black. Color palette: vivid amber #FFA500, deep matte black PCB, translucent acrylic dome grey, tight warm glow halo.
